2. Draw a free-body force diagram for the following.

3. Construct the diagram
a) Construct a series of 3 free-body force diagrams for an object on a slope as the angle of the slope increases from 0 to 90 degrees.

5. Pick and match Work in pairs but fill in your own sheet.
Use the table sheet to record the match between the number of the pictures and the letter of the free-body force diagram.

7. Construct the diagram
1) Construct a series of 3 free-body force diagrams for an object in equilibrium suspended by two wires as the angle of the wires to the horizontal decreases from 70 degrees to 20 degrees.
2) Two objects of the same mass are connected together by a piece of string. One object is placed on a table and the other object is suspended over the end of the table by the string running through a pulley. Construct a series of 3 free-body force diagrams to show what happens as the coefficient of static friction between the object on the table and the table increases from 0 to 1.1. Assume the coefficient of kinetic friction is 90% of the coefficient of static friction.
3) Construct a series of 3 free-body force diagrams for an object in water as the density of the object changes from 70% of the density of water to 100% and finally 130% of the density of water.
